	The current version of GSFIT has the limitation of accepting as valid '''Nparms''' input only '''5''', '''7''', and '''6''', which limits the free parameter search space to the first, 5, 6, or all 7 parameters in the strict order listed above. However, the dimension of the parameter space may be also limited by setting minimum and maximum bonds in the corresponding fields accessible on this page.
